WILLIAM BRIDGEWAT'ER, OF LEICESTER, ENGLAND.

PAPER-FEEDING MACHINE.

SPECIFICATION forming part of Letters Patent No. 685,370, dated October29, 1901.

Application filed June 1, 1900. Serial No. 18,726. (No model.)

To all whom, it nury concern:

Beitknown that LWILLIAM BRID GEWATER, a subject of the Queen of England,and a resident of No. Great Central street, Leicester, in the county ofLeicester, England, have invented certain'Improvements in Paper-FeedingMachines, of which the following is a specification.

This invention has reference to what are known as paper-feedingmachines,and more particularly to that class of such machines in whichthe separating and feeding forward of each successive sheet is efiectedby rollers pressing upon such sheet to buckle or arch it in the mannerwell understood.

The primary object of the invention is to provide means for applying amore sensitive and resilient pressure than heretofore upon the sheets ofpaper, so as to give a lifting tendency to the pressure-rollers.

To this end the invention consists of forming the pressure-rollers withserrated peripheries and in one length, or each roller may consist-of aplurality of collars with serrated peripheries, of rubber or othersuitable mate rial, such rollers being more certain and uniform in theiroperation than the continuous rollers or collars with smooth or ordinaryroughened peripheries, as hitherto used.

Reference is to be had to the accompanying drawings, and to the lettersmarked thereon, forming a part of this specification.

Of the drawings, Figure 1 represents a perspective View of a collarformed in accordance with this invention, and Fig. 2 is a longitudinalsection of same Referring to the drawings, which portray one form of theinvention selected for the purpose of illustration, it will be seen thatthe collar has a sleeve A extending both sides of the body B, the insidediameter of the sleeve being such that it will hold in position on thespindle by its own embracement. The periphery of the collar is serrated,forming a series of teeth 0, the two faces D and E of such teethdifiering in acuteness, the more acute face E facing the direction oftravel. (See arrow in Fig. '1.) With pneumatic collars the periphery isrounded, as illustrated in the drawings; but with solid collars theperiphery is preferably flat.

While I have shown in the drawings and de scribed in this specificationthe preferred form of my invention, one or more of the collarsconstituting a pressure-roller when mounted upon a spindle, my inventionis by no means specifically limited thereto, but is susceptible offurther embodiment without departing therefrom. Forinstance, instead ofthe body B being made pneumatic it may be formed solid with a fiatperiphery, as before stated, and, further, a number of the collars maybe formed on one sleeve, either all pneumatic or all solid or acombination of both, in all instances, however, having serratedperipheries. Furthermore, it is to be understood that my invention isapplicable to all classes of machines provided with pressure-rollers forseparating and feeding sheets of paper and analogous materials.

What I claim is 1. In a paper-feeding machine, pneumatic collars havingserrated and rounded peripheries mounted on a spindle to form apressureroll and adapted to engage successive sheets of paper,substantially as described.

2. In a paper-feeding machine pneumatic collars mounted on a spindle toform a pressure-roll said collars having serrated and roundedperipheries the serrations having their faces of different acuteness,substantially as described.

3. In a paperfecdin g machine pneumatic collars having serrated androunded peripheries and provided with sleeves which clasp the spindle onwhich they are mounted to form a pressure-roll adapted to engagesucc'essive sheets of paper, substantially as described.

4. In a paper-feeding machine non-pneumatic collars having serratedperipheries and provided with sleeves which clasp the spindle on whichthey are mounted to form a pressure-roll adapted to engage successivesheets of paper, substantially as described.

5. In a paper-feeding machine, the combination of pneumatic andnon-pneumatic collars having serrated peripheries, mounted on spindlesto form pressure-rolls adapted to en= gage successive sheets of paper,the serrations on said collars having their faces of differentacuteness, substantially as described.

In testimony whereof I have signed my name to this specification in thepresence of two subscribing witnesses,

WILLIAM BRIDGEWATER.
